92 Claims. (Cl. 93-2) This invention relates to machines for packaging articles and more particularly to a method and machine for packaging relatively soft and compressible articles such as loaves of bread, Whether sliced or unsliced.

The invention contemplates the general improvement and simplification of packaging machines and aims to present a commercially desirable wrapper which, in addition to being qualied to handle a multiplicity of sizes and shapes of baked goods such as are ordinarily produced by large bakeries, is simple to operate and adjust, and will not be injured by inadvertent operation with the parts in disadjustment.

One object ofthe invention is to provide a wrapping machine having means for receiving and individually measuring each article and for feeding a portion of wrapping material thereto from the end of a continuous web in accordance with the size of each measured article.

Another object is to provide a Awrapping ,machine in which .wrapping material is fed and carried upwardly and positioned ln the path of an article advancing to Ithe wrapping mechanism whereby the leading endv of the Wrapper may be carried over the top and down the rear side of the article.

Another object is to provide a machine of this character having means to alter and regulate by means of simple adjustments the amount of overlap of the wrapping material and thetightness 'of the wrapper about the wrapped article, and

more specifically to provide such a machine in which these adjustments may be made during continuous operation of the wrapping mechanism.

A further object is to provide an improved machine of this character, simplev and inexpensive to manufacture and operate, which accommodates different sized articles with a minimum of manual adjustment and which is smooth and quiet in operation and wraps articles by Vmeans of uniform and regular folds. j

Other objects and advantages will become apparent as the'description of the invention proceeds. This description is made in connection with thev accompanying drawings in which like parts are identified by the same numerals of reference throughout the sev'eral views. Although the machine illustrated and described'is primarily intended'for wrapping loavesof bread, the features of theinvention which are embodied in theparticular construction and combination ofA parts are applicable and advantaegous *in In the drawings,

Figure 1 is a plan view with parts removed of a wrapping machine-slicing machine combination embodying the present invention;
